It is true that some women absorb more than others from all forms of HRT local and systemic, as we are all different. However I understand the main difference in the amount absorbed is due to the condition of the vaginal mucous membranes - which is why it is so important that those who only want to use topical/local oestrogen to follow the dosing instructions carefully, to minimnise systemic absorption.
As we have discussed on other threads, if a woman has VA and the vaginal tissues have thinned, then some systemic absorption occurs. After approx 2 weeks the tissues and cells have grown and systemic absorption, although it still occurs is said to be minimal, especially with the 10 mcg patch - although many have said this is not enough to keep symptoms at bay!
Morwenna - re Orthogynest pessaries: I've e-mailed the manufacturers and will post when I have a reply. I do hope it's not bad news for women....
